8. Measuring with the BENNING MM 11
8.1 Preparations for making measuring
Operate and store the BENNING MM 11 only at the specified storage and oper-
ating temperatures conditions. Avoid continuous insulation.
-
Check rated voltage and rated current details specified on the safety meas-
uring leads. The nominal voltage and current ratings of the safety measur-
ing leads included in the scope of delivery correspond to the ratings of the
BENNING MM 11.
- Check the insulation of the safety measuring leads. Discard the safety
measuring leads immediately if the insulation is damaged.
- Check safety measuring leads for continuity. If the conductor in the safety
measuring lead is interrupted, the safety measuring lead must be quaran-
tined immediately.
- Before - at the rotary switch
- a different function is selected, the safety
measuring leads must be disconnected from the measuring point.
- Strong sources of interference in the vicinity of the BENNING MM 11 can
lead to unstable readings and measuring errors.
8.2 Voltage and current measurement
Do not exceed the maximum permitted voltage with respect to
earth potential! Electrical danger!
The highest voltage which may be applied to the jacks,
- COM socket
- jack for V,
, Hz, °C,
- jack for mA range
and the
